分析：android系统设置的部分都在packagesappsSettings目录下面，所以要修改打开‘开发者选项’的‘USB调试’需要修改的部分就在此目录下面
第一步：创建一个广播类 packagesappsSettingssrccomandroidsettings目录下面创建一个DevelopmentReceiver.java接收类
+package com.android.settings;
-
import android.content.BroadcastReceiver;
-
import android.content.Context;
-
import android.content.Intent;
-
import android.provider.Settings;
-
import android.util.Log;
-
public class DevelopmentReceiver extends BroadcastReceiver {
-
@Override
-
public void onReceive(Context context, Intent intent) {
-
String action = intent.getAction();
-
String develepmentKey = intent.getStringExtra("usbDebugKey
